To Increase Size of /var patition.

[walter crasto_1]

Hi,

My /var is almost full & now it's not allowing me to install the OS patches my OS ii HP-UX 11.0. How can I increase the /var size I have 160MB free space on my vg00.

Thanks

Do you have Online JFS ?
if YES
then
man fsadm #Don't remember the syntax
You did it
else
boot into LVM maint mode
lvextend -L extendfs -f vxfs /dev/vg00/rlvol?
reboot
fi

Regds,

What is the present size of /var

Just do a
#du -k /var|sort -nr|more

check any unwanted directores lying in /var.

check /var/adm/syslog
/var/tmp
/var/preserve
/var/mail
/var/crash directories.

check whether you can free some space from those directories.

What all bunles are there on the system.
You can also run the 'cleanup -c 1 ' to commit the patches which are superseeded atleast once.

If everything of the above is not spplicable,check the number of Free PE on the vg00.
If you have online JFS just extend your /var.
Else you will have to umount it and then re-size it which can be done in single user mode.

[MarkSyder]

There are all sorts of things you can get rid of in /var:

> /var/adm/btmp (note use of > - null the file, do not remove it)
> /var/adm/cron/OLDlog
> /var/adm/cron/log
> /var/adm/lp/log
> /var/adm/sulog
> /var/adm/syslog/mail.log
> /var/adm/syslog/syslog.log (having first checked the file for errors or warnings)
> /var/adm/wtmp

If this fails to free enough space you might consider creating new filesystems under /var.

E.g. move /var/tmp into its own logical volume.

Hi walter

#umount /dev/vg00/lvol8

#lvextend -L 676 /dev/vg00/lvol8

#extendfs /dev/vg00/rlvol1

#mount /dev/vg00/lvol8 /var

#bdf

and check, ifnot provide me lvdisplay & fstab

Hi Walter,

if you have not OnLIneJFS then boot in single user mode and

# umount /var
# lvextend -L /dev/vg00/lvolX
# extendfs /dev/vg00/rlvolX
# mount /var

Otherwise see /var/adm/syslog/OLDsyslog.log, mail.log and /var/adm/crash for old crashes.

HTH.

Best regards,
Ettore

Hi,

First of all, you can clean up /var by using the command cleanup -c N. It will remove patches superseded at least N times. (I'd recommend N=2). Previously you should back up /var/adm/sw directory.
If this will not give you enough free space, shutdown the computer to single user mode, extend the logical volume by
lvextend -L XXX /dev/vg00/lvol8
and file system by
extendfs -F {vxfs|hfs} /dev/vg00/rlvol8

Good luck
